TO ALL WHOM IT MAY CONOERN:

Be it known that ROBERT FITTS, Jr., of Fitchburg, in the county ofWorcester, and State of Massachusetts, have invented some new and usefulimprovements in Odice Chair; and I do hereby declare that the followingis a. full, clear, and exact description thereof, which will enablethose skilled in the art to make and use the-same, reference being hadto the accompanying drawings, forming part of this specification, inWhich- Figure 1 represents a revolving chair in one position having'myimproved arrangements for tilting the seat on a spring, and also forsecuring the bent Wood legs. l

Figure 2 represents the same in another position.

Similar letters of reference indicate corresponding parts.

This invention relates to improvements in the construction of orm-chairsdesigned for use in oices and other purposes, and consists, rst, inattaching bent wood legs to a pedestal nut, which receives the screw forraising and lowering the seat and revolving it as desired; .a-nd,secondly, in pivoting the cross-head of the screw to a spider thatsupports the seat of the chair, in such a manner that it may be tiltedto bear on a spring, as hereinafter more particularly described. p

A represents the seat of an arm-chair secured to a. spider, B. C is across-head of a screw, a. Thecrosshead C is pivoted at o to one of thearms of the spider B,'thst is placed at right angles to the front sideof the chair. At the rear end of the cross-head C a. spirel spring c, isset in a cup in such a manner that by tilting the seat A backwards afollower, d, fastened to-the spider, shall press upon the spring to`contract it, and thus make the seat easy and comfortable by itsresistance to the pressure of the occupant. The spring may be placed invarious positions, and made in different forms. The front end of thecross-head is supported against the under side of the spider B at e,when the seat is level, und is provided with an India-rubber or otherlsoft and elastic pad for making the contact'easy when the seat isbrought down to a. level from a tilted position. The screw a works in acast-iron pedestal nut, D, that may be made ornamental. Four legs, E E,made of bent wood, by steaming and shaping,- are secured in the bottomof the pedestal nut D by means of a plate, m, which -is fastened to thenut with screws and nuts s e. The bent legs'E E cross the pedestal nut Dat right angles,

and may be made oftwo or four pieces of wood inserted in recesses formedin the bottom of the nut, as shown clearly in iig. 3. This modeofconstructing and securing the legs of a chair is simple, cheap, andornamental, and very strong and serviceable. y

I claim as new, and desire to secure by Letters TLD-atent- 1. `The bentwood legs E E, in combination 'with the pedestal nut D, constructed andsecured together sub' stan tinlly as described.

2. The cross-head C of the screw a, pivoted to the spider B, in.combination with the seat A, constructed and operating substantially asand for the purpose herein described.

3. The combination of the cross-head O, the spider B, and the spring c,arranged and operating substan-A tially as herein described.

The above specication of my invention signed by me this iifteenth dayof'June, 1867.
